R740 – Left atrial appendage occlusion/excision by suture or device
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
Performs an occlusion or excision of the left atrial appendage by suture or device. This procedure is designated as a 'Sole procedure', meaning it is performed without other concurrent major surgeries. This service is eligible for payment to the surgeon (suffix A), assistant (suffix B), and anaesthetist (suffix C). The fee for the assistant is based on 6 basic units plus time units. The fee for the anaesthetist is based on 7 basic units plus time units. This service includes all common and specific elements of a surgical procedure as outlined in the General Preamble.
When to Use
- Use R740 when performing a standalone left atrial appendage occlusion or excision via suture or device as the primary surgical objective.
- Select R740 for isolated, minimally invasive or open surgical LAA closure when no other major cardiac or thoracic procedure is performed during the same operative session.
Common Pitfalls
- Billing R740 alongside other major cardiac surgical procedures will result in rejection, as it is strictly defined as a 'Sole procedure'.
- Attempting to bill E521 with R740 is incorrect, as E521 is intended for when the LAA closure is performed in conjunction with another major procedure, which contradicts the 'Sole procedure' definition of R740.
Billing Tips
- Ensure that if the LAA closure is performed as part of a larger cardiac surgery, you use the appropriate conjunction code (E521) rather than R740 to avoid audit flags for unbundling.
